What is Launch Control System in Cars and How it Works?

You can change your driving mode by just pressing a button. Each mode is calibrated for optimum traction control, altered gearing, suspension settings, throttle response, and steering. 

High performance cars have powerful engines for rapid acceleration, which can often cause excessive wheel spin and loss of control, especially when starting from a standstill. Such vehicles usually have a dedicated launch control system to prevent this from happening.

Keep scrolling to learn more about launch control in cars and their functionalities.

What Is a Launch Control System?

Launch control is an Advanced Driving Assistance System (ADAS) mostly found in high-performance and sports cars. This feature helps drivers maintain control over the vehicle during quick acceleration from a standstill. 

This feature is designed to produce optimum power and traction to accelerate as fast as possible from a standstill. While the "Control" part emphasises safety, the main focus is acceleration.

What Are The Functions Of Launch Control?

The function of launch control is not limited to minimising wheel spin. It also aids in managing throttle, gear settings, and torque to prevent possible vehicle damage. 

A car with a launch control system has a higher chance of overheating the transmission system and over-revving the engine. This is why it is the most useful for racing cars. 

For instance, in a drag race, having a powerful engine is as important as getting off the line as fast as possible. Here, torque and horsepower play equally important roles. A launch control system focuses on both.

How Does Launch Control Work?

In simple terms, the launch control system should launch you off in the quickest and most hassle-free way possible. But the process that happens, maybe within a fraction of a minute, is not as simple as it sounds. 

  • Firstly, LC ensures that there is no wheel spin. To do so, the system first detects if there is any wheel spin and distributes the power accordingly for adjustment.

  • Then, it needs to ensure that the transmission doesn’t overheat and the engine doesn’t over-rev. 

  • Usually, you press the brake with the left and the throttle with the right foot. 

  • Once the engine revs to a predetermined limit, you let go of the brake and off you go. 

So, in a gist, the launch control system will apply as much power as possible to the wheels and initiate shifts while minimising the wheel spin. 

How to Activate Launch Control?

In most cars, activating the launch control system can be as simple as pushing a button. But, the process involves a little more than just this. After setting up the other features, the process of activation goes something like this: 

  • Press on the brake and hold 

  • Press down on the accelerator and hold until kicked down 

  • Wait until a start flag appears on the driver information panel 

  • Regulate the starting speed and RPM or revolutions per minute 

  • Release the brake while regulating kick down 

  • As the clutch or gear engages, your journey begins

Benefits of Launch Control

Take a look at the following benefits of a launch control system: 

  • It gives the optimal power at the beginning of the movement of a car. 

  • It ensures the engine doesn't over-rev and the gearbox does not heat up.

  • An LC system enhances fuel economy by eliminating unnecessary wheel spin and hop.

FAQ on Launch Control System

What is the difference between a launch control and an anti-lag system?

An anti-lag system’s function is limited to creating an explosion in your car's exhaust to keep the thrust on before turning on the turbocharger.

Is launch control bad for motorbikes?

Modern motorbikes are technologically advanced and can be trusted with modifications and adding new features. Hence, launch control is not necessary for motorbikes. However, when used in moderation, it can give you greater fun and thrill of riding.

Is launch control a necessary car component?

Launch control is not necessary in cars unless it is a sports car. However, it depends on whether the driver will be happy with manually balancing the clutch, transmission, and engine or just pushing a button.

What is the function of a pre-set rev limiter?

The function of a pre-set rev limiter is to discontinue the ignition in the engine beyond a particular rpm to prevent it from revving higher. Rev limiters are typically set between 3500 and 4500 rpm. The limit adjusts automatically once the wheels receive torque.
